I've given up asking for an updated rerun of the Zephyr, so I will now suggest a never done, hopefully brass, SP 4-10-2 Gresley steamer. They recently did the UP 4-12-2 Gresley, so that sound should be available as well as the mechanism. The 5000 series were found pulling heavy freights throughout the SP system. Would be perfect for their next brass Vision loco! I hope.
